Hello,
Recently I have enabled statistics module which works pretty nice.
One thing though I have noticed in xwiki log file is the following
exception occurring periodically

Could someone tell if it's a serious issue and which type of error it
identifies: configuration error or bug in statistics module?
We are running XWiki Enterprise 2.2.4.28034
